Strap for Seamaster Aqua Terra 150M Master Chronometer 41 Yellow Gold / Blue / Tokyo 2020 Olympics

The lug width of the Omega Aqua Terra 522.53.41.21.03.001 is 20mm. This measurement is taken by measuring the distance between the inner shoulders of the pins that connect the strap to the case. It is essential to verify this dimension before purchasing an aftermarket strap, as a 19mm or 21mm lug width will not fit correctly.

For an Aqua Terra in 18-carat yellow gold, alligator leather in cognac or dark brown tones represents the ideal solution from both an aesthetic and functional perspective. Vegetable-tanned calf leather is a versatile alternative that develops a natural patina over time. We advise against absolute black, which is too contrasting with yellow gold, and rubber, which trivializes the preciousness of the case.

To change the strap, you must remove the spring bars (pins) that connect the strap to the lugs of the case. Use a spring bar tool (specific tool for the pins) by inserting it into the small lateral groove of the lug, pushing gently until the pin retracts. Remove the old strap and insert the new one by aligning it with the holes, then reinsert the spring bars until they click into place. Ensure that the strap is positioned symmetrically.

All straps with a 20mm lug width are compatible with this model. Milanostraps.it offers a specific collection of 20mm straps in alligator, calf, shell cordovan and other materials, customizable for size and stitching thread. Each strap is tested for compatibility and fitting on this case.

A quality leather strap, such as alligator or vegetable-tanned calf, typically lasts 3-5 years with daily use and regular maintenance. Durability depends on exposure to moisture, perspiration, climate and frequency of use. A Casati Milano strap with artisanal finishing and hand stitching is designed to last the maximum with proper care: avoid prolonged soaking and treat occasionally with creams specific to leather.
